Silica Microspheres, Streptavidin, 0.5µm

描述

Streptavidin-modified microspheres bind biotinylated ligands easily and with great affinity. They are offered as a 1% dispersion in water.

These silica microspheres are available with a nominal diameter of 0.5µm to allow the researcher to tailor his/her product design for specific assays.

Our non-functionalized silica microspheres are also available in a wide range of sizes. Polysciences' uniform, non-porous silica microspheres are available in diameters of ~150nm to 5µm. The particles typically have size CVs of 10-15%. For applications that require highly stringent CVs (e.g. 2-5%), call for product availability. They are suitable platforms for surface modification with functionalized organosilanes to introduce specific binding sites.
